Lactic acid (LA) is the most predominant industrial product obtained from LAB fermentations, and its production is forecasted to rise as the result of the increasing demand of polylactic acid.

We describe the geochemistry and microbial diversity of a pristine environment that resembles an acid rock drainage (ARD) but it is actually the result of hydrothermal and volcanic influences.

Field performance of hermaphrodite papaya plants obtained through molecular selection and micropropagation.

It was observed that through both PCR methods the fingerprinting profile of a subset of samples was identical. The genetic analyses revealed that non-Arabica coffee displayed greater genetic variation than Arabica coffee did.

Los parvovirus en los géneros Bocaparvovirus, Erythroparvovirus y Tetraparvovirus son los únicos que se sabe que están asociados con primates humanos y no humanos según estudios y casos clínicos. Aquí, la presencia de estos agentes patógenos se evaluó por PCR en sangre y heces de 55 monos aulladores, 112 monos de cara blanca, 3 monos ardilla y 127 monos araña en Costa Rica y El Salvador.

Unlike other issues that have a widespread impact on thehumanity (finance, health and transport ...), knowledge of activitiesRelevant microbials, how they impact our lives and how they canseize for the benefit of humanity, 'literacy inMicrobiology lacks in the general population, and in the same that They constitute decision makers.

The development of efficient and fast analytical tools that allowthe differentiation between species, subspecies and varieties of plants is arelevant topic. Here we describe a multivariate model based on footprintsDigital capable of discriminating between subspecies and plant varietiesMedicinal Chamaecrista nictitans, a rare species distributed in Costa Rica.

Many insects have been associated with actinobacteria in protective symbiosiswhere antimicrobial metabolites inhibit host pathogens. WithoutHowever, the microbiota of neotropical insects like the bee withoutTetragonisca angustula sting is little explored. This meliponid beewidely distributed in Latin America is traditionally exploited for itsHoney due to its ethno-pharmacological properties and its provenantimicrobial activity.

Here we report the chemical and microbial characterization of the waterssurface of a hydrothermal vent rich in carbon dioxideknown in Costa Rica as Borbollones, located in the National ParkTenorio Volcano.

The archive of the University of Costa Rica maintains a French collectionof drawings and lithographs of the nineteenth century in which biodegradation is aimportant factor. Of course we focus on isolating and identifying theFungal species responsible for the biodegradation of the collection anddetermine your cellulite activity.

Due to its role in the metabolic control of carbon and energy, theCra protein has been one of the most studied prokaryotic regulators ofthe last 30 years. However, the nature of the metabolic effector thatIt governs its ability to bind to DNA, remains controversial.
